SPECIFICATION forming part of Letters Patent No. 260,189, dated June 27,1882.

Application filed February 25, 1882. (No model.) I

To all whom it may concern Be it known that I, RUDOLPH P. GERLACH, ofOleveland, in the county of Cuyahoga and State of Ohio, have invented acertain new and useful Improvement in Flue-Oleaners; and I do herebydeclare that the following is a full, clear, and complete descriptionthereof.Y

The improvement above alluded to in lluecleaners consists of a new andnovel device for attaching the spring-arms of the cleaner to the head ofthe implement, so that the said arms shall be strong and durable intheir connection therewith and not liable to break at their junctionwith the head.

A full and complete description of the improvement will be found in thefollowing speciication and illustrated by the annexed drawings, making apart of the same, in which drawingsv Figure l represents a side view ofthe improved ilue-cleaner. Fig. 2 is yan end view of the head of thecleaner, and showing a transverse sectional view of the arms attachedthereto. Fig. 3 is a detached section. Fig. 4 is a longitudinaltransverse section.

Like letters of reference refer to like parts in the several views.

Inasmuch as the Scrapers, guides, and springarms of the implement formno part of the improvement above referred to, a brief description onlyof said parts is deemed essential in this place, which is substantiallyas follows:

A are the spring-arms, to the eXtreme ends of which are secured theScrapers B by means of angle-irons O. To said Scrapers are at-v tachedrespectively guides D, provided with wings, whereby they are riveted tothe scrapers, substantially as shown in Fig. 1.

The head of the implement consists of a trian gular-shaped block, F, ineach side of which is a recess adapted in width and-depth to receive theend of a spring-arm, as seen in Figs. 2 and 3, in which it isclose-fitting.

From the center of each recess projects a stud, a, which may be eitherround, oblong, or of other form, and made to fit closely7 in acorresponding hole in the spring-arm, through which the stud projectsfar enough to permit of its being riveted down upon the spring forsecuring it to the head, as seen in Fig. 3. It is not essential,however, that the stud be riveted for the purpose specified.

It will be observed that upon the head,

which is tapering, is fitted a ferrule, G. On the inner side of theferrule are arranged longitudinally three ribs, H, corresponding to thethree sides of the triangular head F, against which sides and thesprings secured thereto the three ribs respectively press on forcing theferrule onto the head by means of the nut I, screwed upon the screw-stemJ of the head, thereby rmly binding the ends of the springarms betweenthe said head and the ribs of the ferrule, so that they cannot becomedisplaced laterally from the head, nor be withdrawn therefrom nor pushedinward, for reason of the stud a being in the hole in the spring-arm, asabove mentioned, which elIectually secures the spring-arms in place.

Heretofore the spring-arms have been secured to the head by beingdovetailed or mortised therein. To do this requires a portion of theedges of the arm to be cut away to form the dovetail or mortise, therebynarrowing the spring at its junction with the head, at which point isexerted the greatest strain upon the springs, causing them to break atthat particular place.- This lliability to break is wholly avoided byconnecting the spring,

arms to the head, as above described, and

shown in the drawings, as the full strengthpf the metal of the arm isleft to resist the strain to whichit may be subjected. No part of thearms subject to strain is weakened by being lcut away to make itsconnection with the head,

which head and stem J are cast in one piece.

Itis not essential that the head and stem be in one piece. The stem maybe of wroughtiron and inserted in the head in any suitable Wy- What Iclaim as my invention, and desire to secure by Letters Patent, is

In due-cleaners the ferrule G, with interior longitudinal ribs, H,forming an integral part thereof, a triangular-shaped block, F, having arecess in the sides thereof to receive the edges of the spring-arms, anda stud, a, extending therefrom and through said arms, in combinationwith the nut I and`stem,arranged substantially as and for the purposeset forth.
